Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box; for Tesla Model S, it's usually found under the dashboard or in the trunk.
Identify the wiper fuse (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Check and Replace Wiper Relay

Locate the relay box; check the owner's manual for the location of the wiper relay.
Remove the relay by pulling it straight out.
Test the relay using a multimeter, or replace it with a new relay if it shows no continuity.

4. Inspect and Replace Wiper Motor

Remove the plastic cover or cowl where the wiper motor is located.
Disconnect the electrical connector from the wiper motor.
Remove the mounting bolts securing the wiper motor (usually Torx screws).
Carefully pull the wiper motor out and inspect it for damage.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.

5. Reconnect and Test

Reconnect the negative battery terminal.
Turn on the ignition and test the wipers to ensure they operate correctly.
If applicable, refill and test the windshield washer fluid system.
